Exchange names: through the exchange of names we become part of the same family, in this case the family is called the house of Israel. We are gathered in spiritually and then physically if necessary. In the first three steps we become one physically and spiritually and then in step 4 we are gathered into one family. Gods name is YHWH. In making a covenant with Abram He gave him an H and he became Abraham and He gave Sarai another H and she became Sarah and God became known as the God of Abraham.
The covenant terms are actually all of the word of God for we are told in Isa 55:11
So shall My word be that goeth forth out of My mouth; it shall not return unto Me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it.God has no doubt about His word and if we have a covenant relationship then we will also have no doubt about the word of God. We will grow to the point where we will only say things that are in harmony with the word of God. This means no more backbiting or murmuring or worry or fear etc.
A memorial meal we are familiar with but the way we have approached communion needs improvement because we have not understood the true nature of the covenant relationship.
Plant a memorial, such as a tree or make some permanent reminder as an altar of stones. Notice that after we become one and join the house of Israel based on the word of God then we have two remindersthe scar (symbolic of a broken heart) and this memorial (plant the word in your heart)to remember the covenant. Remember means to do.
